With these and other objects in view,

the invention consists of certain novel featuresof construction, as will be more fully described, and particularly pointed out in the appended claims' In the accompanying drawings Figure 1 is a perspective view of a finger ring constructed in accordance with my invention.

Figure 2 is a perspective view of the head portion of the ring after it has been swaged to provide spring abutments thereon.

fl igure 3 is a perspective view showing the head member as bent into substantially its finished shape.

Figure 4 is a perspective. view of the top plate of the head member.

Figure 5 is an enlargedperspectiveview showing the end portion of the band memher which extends into the head.

Figure 6 is a sectional side elevation of the head and band member in assembled contracted position.

Figure 7 is a plan view of the resilient means or spring for contracting the band.

Figure 8 is a view similar to Figure 6 showing the band in expanded position.

It is found in practice that finger rings whichare made of a size to fit the finger where finger rings are commonly worn at the point where the finger joins the hand that oftentimes the band will not pass over the knuckle of the wearer and thus it is necessary to make the ring several sizes larger than an actual wearing fit, in order that the ring may be passed 7 over the knuckle into wearing position and in order that a more perfect fit may be obtained for the ring in its wearing position, I have constructed a band member which has one or both of its ends slidable relative to the head or ornamental portion of the ring and provide resilient meansby which the band may be opened up or extended topass over the knuckle and which resilient or'spring means may act to contract the band after it has my expansible" ring. hereln illustrated at12'in' Figure 2 as being been passed over the knuckle to inorepn fectly fit the ring wearing 'p'ortion of the finger; and the following isia detailed de-' scription of the presentembodiment ofmy in vention' and showing one construction by which these advantageous results may be produced 'w v i I With reterenceto the drawings, lOdesig nates the head and 11 the band member of This head member is bent orformed into shape and is shown; as

being provided with upstandii'ig abutments 13 which may be formed in anyJsuit-a ble manner but which are "here illustratedas being formed by swaging the plate 12 between dies to draw up the abutments 13 integral therewith after which the plate is bent as illustrated at 1 1, Figure 3, into sub stantially channel shape having a bottom wall 15 and side walls 16 which are folded as at 17 to receive a top plate 18 with coopcrating inwardly turned edges 19 which top plate may be slid into the grooves formed by the folding over of portions 17 and these inter engaging portions are firmly pressed togetherto prevent the top plate from being Withdrawn from the bottom member 14.

' The end portions 20 of the band member are pierced out as at 21 forming an abutment web 22at the end of they band, and this end portionextends into and is housed in the head, as illustrated in Figure 6, and the abutments 18 of the head extend into the pierced opening 21 and serve to limit the 5 relative movement of the band end and head. Between the abutment 18 and the web 22 a spring 23 is positioned tending to press the end portion 20 into the head towards each other and contract the size of the ring. I

have also illustrated in Figure 6 this con-' struction as duplicated at both ends of the band portion which is found preferable, but it is understood that where a very slightenlargement is desired but one end portion of the band andhousing need'bev so constructed as to slide, and in which case thejother end of the band may be securedto the housing.

is directed head and slidable relatively thereto, an abut ment carried by and within said head extending into said opening, and a sprmg aeting between said abutment and band end portion to move said end into said head and contract the ring.

'2. A finger ring comprising a hollow head, a single piece band'member having separable" ends slidably extending into said head from opposite sides thereof, said each end having an opening therein, a pair of abutments carried by and within said head and one extending into the opening in one of said band ends and the other extending into the opening in the other or" said band ends, and

springs in said openings acting between said head -abutments and band for tending to cause said band endsto slide in said head toward each other and contract the size of I the ring.

3. A finger ring comprising a single piece band member having separable ends with an opening in each end portion spaced from the end wall thereof, a hollow head housing said separable ends and having integral abutments therein spaced from the ends of said housing and each extending into one of said openings in said band end portion, and springs acting between said head abutments and the end walls of the openings to slide said band ends toward each other in said housing and contract the ring.

4. A finger ring comprising a hollow head, a band member having an end with an opening therein extending into said head and slidable relatively thereto, an abutment'carried by and within said head extending into said opening, and resilient means acting between said abutment and band end portion to move said end into said head and contract the ring.

In testimony whereof I afliX my signature.
